Впервые для себя заказал аккумуляторы PANASONIC NCR18650PF. Доставка в Украину за 2 недели. Первое, что немного огорчило, так это то, что аккумуляторы пришли с датой производства февраль 2018г. Дата конечно не очень свежая, поэтому при разряде-зарядке аккумуляторов током в 1А до 2900мАч не дотянул ни один аккумулятор. Среднее значение 2800-2830мАч.
-----------------------------
For the first time I ordered PANASONIC NCR18650PF batteries for myself. Delivery to Ukraine in 2 weeks. The first thing that upset me a bit was that the batteries came with a production date of February 2018. The date, of course, is not very fresh, so when discharging and charging batteries with a current of 1A up to 2900mAh, not a single battery lasted. The average value is 2800-2830mAh.

Since genuine Panasonic batteries are smooth from the top, these have markings from spot weldings, so my guess is that they propably are genuine but recycled, so they are taken out from an another system and sold cheap 2nd hand. Thats one reason why you see so much of fluctuations on their capacity or much lower than should. Real Panasonic cells can be charged +2k cycles and still they show reasonable capacity left. So cells can be sold 2nd time since there might still be left lot of capacity.
You can buy from eBay those green Panasonic cell covers so once damaged cells can be made look shiny new once the wrapping is renewed.
Since there is so much of rumours about the genuinity of the batteries, these sellers should be open about it and tell the truth. Untill then, buyers be aware ! (Posted on 19-01-20)

They do get a bit warm with sustained current draw no where near max. I think the 10a rating is absolute max and cell would probably be extremely hot. At about 7A they seem to work ok just warm. (Posted on 16-12-19)

Only been through about 7 cycles, drawing about 7A max per cell, but usually only about 5A. Results are the cells get pretty damn hot. and already 3 of the cells have completely failed, showing 0 volts. (Posted on 24-12-18)

Test range ,i get over 110km with speed on average of 20-25 km/h with citycoco scooter ,range from driving continous 45km and brake 1 h ,and driving again 45 km, next day over 20km driven ,and still some capacity left (Posted on 17-08-18)

Test them , with citycoco scooter ,range over 90 km after 1 cicle

Bought 150 pieces in two orders and sample tested for consistency. Even though the batches were of different age (about 3-5 months apart) the samples tested very consistent around 2850-3000mAh @1A CC charge/discharge. Even out of the box, the voltages very pretty much the same at around 3.45 - 3.55V. I used the cells to refurbish 3 electric bicycle batteries which had pouch type LiPos before and it all worked out very well. Even after a dozen cycles, there is no noteworthy drift. I've seen far worse on much more expensive cells. Spot welding works excellent. For the low price, these sure can't be beat. I'd definitely buy again! (Posted on 27-04-18)

Bought 50 cells for Bike-Battery, worked well.
Bad BMS discharged whole pack during Wintertime down to 0.5 Volts per cell.
Wanted to put the Cells to the waste-bin, but tried to recharge one Cell (outside, would they explode???). Could be charged to 4.2 Volts. Put the Cell into a cheap AH-Tester with 0.5 Amps: it showed 3000 mAh!!! Tried it with all 50 cells: All of them are Working, no heating during Charging (typical for old cells...)
Amazing! (Posted on 20-04-18)

Ordered 98 pieces for 14s7p ebike battery, tested each one and are in the 2750-2900 mAh range, you can get max capacity only if you charge/discharge as per specs(do not recommend for long life).
Best Japan battery for the price!
Thank you NKON, I will buy more fore sure! (Posted on 15-09-17)

Bought 30 pieces of these batteries to build two batteries of format 3S5P,
to power the Lowrance fish finders, lead batteries no longer want to use.
Capacity 2900 chose the price (3400 be more expensive), the capacity of the measurement, the battery was made in January 2017. Delivery by mail Germany 2 weeks (fantastic!!!).(Posted on 12-08-17)

I bought a few batteries Panasonic & Eneloop which of course were of premium quality.Most of all NKON is a seller that you deserve to deal with.
Excellent communication and fast delivery.Thanks NKON, I'll deal with you again. (Posted on 21-02-17)

Ordered 91 cells for 13S7P ebike battery (48V, 20,3Ah).
Shipping was very fast 3 days to Czech Rep. by DPD.
4 Cells were tested for capacity and they correspond to described 2900mAh (Discharged @ 1A down to 2,75V) with almost no deviation => HIGH QUALITY ORIGINAL CELLS:) Everything perfect....

Panasonic NCR18650PF 3.7V 2900mAh--max drain 10A-- batteries very good !!!!! I am very satisfied!!. very good quality batteries !!! I recommend buying on NKON site, because respects what it promises !! thanks Nkon (Posted on 13-04-16)

Panasonic NCR is the best 18650 battery cells in the world. Also Tesla car model S have the same, underfloor. With this kind of cells I perform the best e-bike revision ever. I have only happy clients ! Also NKON is the best company ever ! (Posted on 21-09-15)

Bought 32 of these tested them all for capacity with an original Imax B6mini (also form Nkon). Discharged @ 2A down to 3V these batteries average to 2749,4 mAh with stdev of 15,1 mAh. These are good highcap batteries, as can be expected. (Posted on 26-03-15)
